用石英热释光法测定淮北白浆土形成年龄。结果表明,白浆层作为晚更新世末期的堆积,形成于距今1万年左右,粘化层是晚更新世早期的庐山一大理间冰期残积成土的,年龄在4.5—13万年间。年龄结果说明整个白浆土土体属两次土壤发生学循环的产物。
Determination of age of formation of albic soil from Huaibei by quartz thermoluminescence. The results show that the albic layer was deposited as the late Pleistocene and was formed about 10 000 years ago. The viscous layer is the later Lushan-Dali interglacial stratum in the late Pleistocene, with an age of 4.5-13.0 years. The age result shows that the whole white soil is a product of two cycles of soil cycle.
